Abstract
Es wird ein Luftsackgewebe vorgeschlagen, bei dem zur Erhöhung der Haftreibung der Fäden an den Kreuzungspunkten von Kette und Schuß kristalline und/oder amorphe Teilchen in mindestens einen Teil der zwischen den Kreuzungspunkten befindlichen Öffnungen eingelagert sind. Das Luftsackgewebe kann am Foulard dadurch hergestellt werden, daß eine Bahn des Rohgewebes durch eine wäßrige Dispersion kolloidaler Kieselsäure hindurchgeführt und anschließend getrocknet wird. Das Gewebe wird zur Herstellung von Airbags verwendet.An airbag fabric is proposed in which crystalline and / or amorphous particles are embedded in at least part of the openings between the crossing points in order to increase the static friction of the threads at the crossing points of warp and weft. The airbag fabric can be produced on the padder by passing a web of the raw fabric through an aqueous dispersion of colloidal silica and then drying it. The fabric is used to make airbags.
Description
Die Erfindung betrifft ein Luftsackgewebe, bei dem aus synthe tischen Fasern und/oder Filamenten hergestellte Kett- und Schußfäden in solcher Dichte miteinander verwoben sind, daß die zwischen ihren Kreuzungspunkten freibleibenden Öffnungen eine mindestens mikroporöse Struktur im Rohgewebe ergeben.The invention relates to an airbag fabric in which synthe table fibers and / or filaments produced warp and weft threads are so closely interwoven that those between them Openings that are free of crossing points are at least microporous Structure in the raw fabric.
Die Erfindung betrifft ferner ein Verfahren zur Herstellung des Luftsackgewebes der vorgenannten Gattung sowie dessen Verwendung.The invention further relates to a method for producing the Airbag fabric of the aforementioned type and its use.
Die zum Schutz von Fahrzeuginsassen bekannten, aufblasbaren Luftsäcke oder Airbags werden aus mindestens zwei Lagen eines für diesen Zweck gefertigten Spezialgewebes hergestellt, die entweder miteinander vernäht oder verwoben werden. Zwischen den mindestens zwei Gewebelagen ist mindestens eine Kammer gebildet, die durch Gasbefül lung bei einem Unfall aufgeblasen wird. Da das Aufblasen eines solchen Luftsacks innerhalb eines extrem kurzen Zeitraumes im Millisekundenbereich erfolgt, werden auf das Luftsackgewebe, insbesondere im Bereich der Verbindungszonen zwischen den oberen und unteren Gewebe lagen, hohe Scherbelastungen ausgeübt, die zu einer Verschiebung der relativen Lage der Kett- und Schußfäden zueinander führen können, wodurch die zwischen den Kreuzungspunkten der Kett- und Schußfäden freibleibenden Öffnungen an besonders belasteten Stellen des Gewebes vergrößert, an anderen Stellen dagegen verkleinert werden. Besonders groß ist die Gefahr bei genähten Verbindungen zweier oder mehrerer Gewebelagen, aber sie besteht auch bei verwobenen Verbindungen. Durch die Bereiche mit vergrößerten Öffnungen findet eine deutlich erhöhte Gasabströmung statt, die, auch wegen der erhöhten Gastemperaturen, zu Gewebeschädigungen und letztlich zum Versagen des Luftsackes führen kann.The inflatable, known for the protection of vehicle occupants Air bags or airbags are made up of at least two layers for one this purpose manufactured special fabric that either sewn or woven together. Between the at least two Fabric layers is formed at least one chamber by gas filling inflation in an accident. Because inflating such a Air bags within an extremely short period of time in the millisecond range takes place on the airbag fabric, especially in Area of connection zones between the upper and lower tissues were high shear loads, which led to a shift of the relative position of the warp and weft threads can lead to each other, whereby the between the crossing points of the warp and weft threads free openings in particularly stressed areas of the fabric enlarged, but reduced in other places. Especially the danger is great when sewing connections of two or more Fabric layers, but it also exists with interwoven connections. By the areas with enlarged openings find a significantly increased one Gas outflow takes place, also because of the elevated gas temperatures Damage to the tissue and ultimately lead to the failure of the airbag can.
Bei gewöhnlichen, locker konstruierten Geweben, Gewirken und Gestricken ist es bekannt, diese instabilen textilen Flächengebilde schiebefest auszurüsten, indem man sie mit Polymerisaten, z. B. mit Polyacrylat- oder Polymethacrylat-Dispersionen, besprüht und nach Aushärtung dieser Polymerisate weiterverarbeitet.For ordinary, loosely constructed fabrics, knitted fabrics and Knitted, it is known, these unstable textile fabrics equip sliding resistant by adding them with polymers, e.g. B. with Polyacrylate or polymethacrylate dispersions, sprayed and after Curing of these polymers processed.
Bei Luftsackgeweben ist jedoch eine vollständige Schiebefest machung nicht angezeigt, weil dadurch die Weiterreißkraft, ein wichtiges Sicherheitskriterium des Gewebes, unzulässig verringert werden würde. Um hohe Weiterreißkraft-Werte zu erreichen, ist ein geringfügiges Verschieben der Kett- und Schußfäden relativ zueinander unerläßlich.With airbag fabrics, however, it is completely slip-resistant This is not indicated because of the tear force important safety criterion of the fabric, impermissibly reduced would be. To achieve high tear strength values, is a slight shifting of the warp and weft threads relative to each other essential.
Der Erfindung liegt die Aufgabe zugrunde, ein Luftsackgewebe bereitzustellen, bei dem die Haftreibung zwischen Kett- und Schußfäden an den Kreuzungspunkten dieser beiden, die Gewebestruktur bildenden Fadensysteme so erhöht wird, daß zwar das Verschieben der Fäden unter Scherbeanspruchung deutlich erschwert, aber nicht vollständig unter bunden wird, so daß die Weiterreißkraft des Gewebes nicht unzulässig reduziert wird. Die erhöhte Haftreibung zwischen den Fäden soll auch nach einer Beschichtung oder Appretur erhalten bleiben, und das Luftsackgewebe soll trotz der erhöhten Haftreibung der Fäden eine ausreichende Flexibilität besitzen, damit ein aus dem Gewebe herge stellter Luftsack klein zusammengefaltet werden kann und in den heute üblichen Airbag-Modulen untergebracht werden kann. Schließlich soll die Erhöhung der Haftreibung zwischen den Fäden des Luftsackgewebes reproduzierbar und in dem für Kraftfahrzeuge geforderten Temperatur bereich zwischen -35 und +85°C temperaturwechselbeständig und 15 Jahre lang alterungsbeständig sein. Die zur Erhöhung der Haftreibung verwen deten Materialien müssen recyclingfähig sein.The invention has for its object an airbag fabric To provide the static friction between warp and weft at the intersection of these two, which form the tissue structure Thread systems is increased so that the threads move under Shear stress significantly more difficult, but not completely below is tied so that the tear strength of the fabric is not inadmissible is reduced. The increased static friction between the threads should also after coating or finishing, and that Airbag fabric is said to be a despite the increased static friction of the threads have sufficient flexibility so that a fabric is available airbag can be folded up small and in today usual airbag modules can be accommodated. After all, it should the increase in static friction between the threads of the airbag fabric reproducible and at the temperature required for motor vehicles range between -35 and + 85 ° C resistant to temperature changes and 15 years be long-lasting. Use to increase static friction Materials must be recyclable.
Diese komplexe Aufgabe wird erfindungsgemäß bei einem Luftsack gewebe der eingangs genannten Gattung dadurch gelöst, daß kristalline und/oder amorphe Teilchen in mindestens einem Teil der zwischen den Kreuzungspunkten von Kette und Schuß befindlichen Öffnungen eingela gert sind.According to the invention, this complex task is accomplished with an airbag tissue of the type mentioned solved in that crystalline and / or amorphous particles in at least part of the between the Crossing points of chain and weft located openings are.
Die Einlagerung der kristallinen und/oder amorphen Teilchen führt zu einer Aufrauhung der Struktur des Gewebes und zu einer Erhöhung der Haftreibung der Kett- und Schußfäden an den Kreuzungspunkten der beiden Fadensysteme, ohne daß ein für die erforderliche Weiterreiß kraft des Gewebes unerläßliches Verschieben der Fäden vollständig unterbunden würde.The inclusion of the crystalline and / or amorphous particles leads to roughen the structure of the fabric and increase the Stiction of the warp and weft threads at the crossing points of the two thread systems without one for the required tearing due to the fabric, essential displacement of the threads completely would be prevented.
Vorzugsweise bestehen die kristallinen und/oder amorphen Teilchen aus unbrennbarem anorganischem Material, insbesondere aus kationak tivem Siliciumdioxid, besonders bevorzugt aus kolloidaler Kieselsäure. Die kolloidale Kieselsäure besitzt eine Teilchengrößenverteilung, die für die vorwiegend mechanische Einlagerung der Teilchen in die mikro poröse Struktur des Luftsackgewebes besonders gut geeignet ist.The crystalline and / or amorphous particles preferably exist Made of non-flammable inorganic material, especially cationic tive silicon dioxide, particularly preferably from colloidal silica. The colloidal silica has a particle size distribution that for the predominantly mechanical storage of the particles in the micro porous structure of the airbag fabric is particularly suitable.
Die Kett- und/oder Schußfäden des Luftsackgewebes bestehen vorzugsweise aus Polyamid oder Polyester, wobei die Verwendung texturierter Garne wegen der von Haus aus größeren Haftreibung, verglichen mit untexturiertem Garn, bevorzugt wird.The warp and / or weft threads of the airbag fabric are made preferably made of polyamide or polyester, the use textured yarn because of the inherently greater static friction, compared to untextured yarn, is preferred.
Vor der Einlagerung der kristallinen und/oder amorphen Teilchen liegt das Rohgewebe vorzugsweise in Form eines unbeschichteten Flach gewebes vor, besonders bevorzugt wird aber ein zweilagiges, teilweise miteinander verwobenes oder vernähtes Doppelgewebe.Before the incorporation of the crystalline and / or amorphous particles the raw fabric is preferably in the form of an uncoated flat fabric, but a two-ply, partial is particularly preferred interwoven or sewn double fabric.
Nach der Einlagerung der kristallinen und/oder amorphen Teilchen wird das Luftsackgewebe vorzugsweise mit einer Beschichtung oder Appretur aus polymerem Material versehen, die vorzugsweise aus einem Silikon besteht.After the incorporation of the crystalline and / or amorphous particles the airbag fabric is preferably coated or Finishing made of polymeric material, preferably from a There is silicone.
Die Haftreibung zwischen den beiden die Gewebestruktur bildenden Fadensysteme Kette und Schuß ist an den Kreuzungspunkten um mindestens 5% größer als diejenige von unbehandeltem Gewebe gleicher Konstruk tion.The static friction between the two forming the tissue structure Thread systems warp and weft is at least at the crossing points 5% larger than that of untreated tissue of the same construction tion.
Das erfindungsgemäße Luftsackgewebe wird aus einem porösen oder mindestens mikroporösen Synthetik-Rohgewebe hergestellt und am Foulard naßchemisch ausgerüstet. Bei dem erfindungsgemäßen Verfahren wird eine Bahn des Rohgewebes durch eine wäßrige Dispersion kolloidaler Kiesel säure hindurchgeführt, danach getrocknet und später gegebenenfalls mit einem Polymer zusätzlich beschichtet. Die Gewebebahn wird den Foulard in an sich bekannter Weise kontinuierlich über angetriebene Walzen paare und nicht angetriebene Umlenkwalzen zugeführt, mit einer Geschwindigkeit von maximal 150 m/Min., überschüssige Dispersion wird mittels Quetschwalzen abgequetscht, und die Trocknung erfolgt eben falls in bekannter Weise in geschlossenen oder offenen Systemen, unter Zufuhr von Wärme.The airbag fabric according to the invention is made of a porous or at least microporous synthetic raw fabric made and on the foulard equipped with wet chemistry. In the method according to the invention, a Path of the raw tissue through an aqueous dispersion of colloidal pebbles acid passed through, then dried and later optionally with additionally coated with a polymer. The fabric web becomes the foulard continuously in a manner known per se via driven rollers pairs and non-driven deflection rollers fed, with a Maximum speed of 150 m / min, excess dispersion will squeezed off by squeeze rollers, and the drying takes place if known in closed or open systems, under Supply of heat.
Die verwendete wäßrige Dispersion weist vorzugsweise eine Konzen tration von 0,5 bis 35 Gew.-% Kieselsäure auf. Der pH-Wert der wäßrigen Dispersion liegt vorzugsweise im sauren Bereich, ist also kleiner als 7.The aqueous dispersion used preferably has a concentration tration of 0.5 to 35 wt .-% silica. The pH of the aqueous dispersion is preferably in the acidic range, that is less than 7.
Besonders vorteilhaft ist es, wenn die wäßrige Dispersion mit kationischen und/oder nichtionischen Appreturmitteln verträglich ist, weil dann dem Tauchbad im Foulard gleichzeitig noch weitere Textil hilfsmittel zugegeben werden können.It if the aqueous dispersion with cationic and / or nonionic finishing agents is compatible, because then the textile immersion bath in the foulard at the same time tools can be added.
Vorzugsweise wird das mit der wäßrigen Dispersion behandelte Luftsackgewebe nach dem Trocknen mit einem Polymer imprägniert und/oder laminiert, vorzugsweise mit einem Silikon.Preferably, the one treated with the aqueous dispersion Airbag fabric impregnated with a polymer after drying and / or laminated, preferably with a silicone.
Das erfindungsgemäße Luftsackgewebe wird vorzugsweise zur Her stellung von Kfz-Insassen-Rückhaltesystemen, insbesondere Seiten- Airbags, verwendet.The airbag fabric according to the invention is preferably the Her provision of vehicle occupant restraint systems, in particular side Airbags used.
Bei der Gewebeprüfung kann das Maß des Widerstandes, den die Gewebestruktur dem Verschieben der Fadenkreuzungen entgegensetzt, näherungsweise durch die Bestimmung der Kammausziehkraft gemäß DIN 53 857 T1 ermittelt werden. Die Größe der Kammausziehkraft wird durch die Haftreibung zwischen den beiden Fadensystemen Kette und Schuß an ihren Kreuzungspunkten bestimmt. Je höher diese Haftreibung ist, um so größer ist der Widerstand gegen ein Verschieben der Gewebestruktur. Die erfindungsgemäße Verbesserung der Haftreibung zwischen Kette und Schuß an ihren Kreuzungspunkten wird nur bis zu einem Grad bewirkt, bei dem die verwendeten kristallinen und/oder amorphen Teilchen die mikroporösen Öffnungen nahezu vollständig ausfüllen.When testing tissue, the degree of resistance that the The fabric structure opposes the shifting of the crosshairs, approximately by determining the comb extraction force according to DIN 53 857 T1 can be determined. The size of the comb extraction force is determined by the Stiction between the two thread systems warp and weft on their Crossing points determined. The higher this static friction, the more the resistance to displacement of the tissue structure is greater. The improvement of the static friction between chain and Shot at their crossing points is only effected to a degree in which the crystalline and / or amorphous particles used Fill in microporous openings almost completely.
Die nachfolgende Graphik gibt die relative Kammausziehkraft des erfindungsgemäß eingesetzten Rohgewebes (Standard) aus Polyamid-6.6 und des erfindungsgemäß behandelten Luftsackgewebes (Kieselsäure) bei Verwendung unterschiedlich konzentrierter wäßriger Kieselsäuredisper sionen (5, 10, 15 und 20 Gew.-%) wieder. Aus der Graphik wird deut lich, daß bei einer Behandlung des Luftsackgewebes mit einer 5%igen Kieselsäuredispersion bereits 60% der maximalen Kammausziehkraft erreicht werden, während mit einer 10%igen Dispersion 70% der maximalen Kammausziehkraft erreicht werden, mit einer 15%igen Dispersion bereits mehr als 95% und mit einer 20%igen Dispersion fast 98% der maximalen Kammausziehkraft.The following graphic shows the relative comb extraction force of the Raw fabric used according to the invention (standard) made of polyamide-6.6 and the airbag fabric (silica) treated according to the invention Use of differently concentrated aqueous silica disper ions (5, 10, 15 and 20 wt .-%) again. The graphic becomes clear Lich that when treating the airbag fabric with a 5% Silica dispersion already 60% of the maximum comb extraction force can be achieved, while with a 10% dispersion 70% of the maximum comb extraction force can be achieved with a 15% Dispersion already more than 95% and with a 20% dispersion almost 98% of the maximum comb extraction force.
Aus diesen Werten ergibt sich, daß es mit Hilfe der Erfindung tatsächlich gelingt, die Haftreibung zwischen Kett- und Schußfäden deutlich zu erhöhen, ohne die Verschiebbarkeit der Fadenkreuzungen unter Scherbeanspruchung vollständig zu unterbinden, so daß die Weiterreißkraft erhalten bleibt. Das erfindungsgemäße Luftsackgewebe läßt sich mit Silikon und anderen Polymeren beschichten und behält gleichwohl eine ausreichende Flexibilität, um klein zusammengefaltet zu werden. Die erreichbare Erhöhung der Haftreibung ist reproduzier bar, das Produkt ist zwischen -35°C und +85°C ausreichend temperatur wechselbeständig und alterungsbeständig, und die verwendeten kristallinen und/oder amorphen Teilchen, vorzugsweise SiO2, sind recyclingfähig.From these values it follows that the invention actually succeeds in significantly increasing the static friction between warp and weft threads without completely preventing the crosshairs from shifting under shear stress, so that the tear force is retained. The airbag fabric according to the invention can be coated with silicone and other polymers and still retains sufficient flexibility to be folded up small. The achievable increase in static friction is reproducible, the product is sufficiently temperature-resistant and age-resistant between -35 ° C and + 85 ° C, and the crystalline and / or amorphous particles used, preferably SiO 2 , are recyclable.
